ROLLER-SKATE Specification of Letters Patent.

Application filed August 29, 1908.

Patented Aug. 17, 1909.

Serial No. 450,852.

To all whom it may concern.'

Be it known that I, JEREMIAH H. HOLLAR, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Roller-Skates, of whichthe following is a specification.

One of the objects of this invention is to provide improved means foryieldingly holding the axles at right angles to the main frame.

Another object is to improve t-he means for supporting the axle.

The invention also relates to the other improvements in roller skateshereinafter set forth.

`In the accompanying drawings, Figure 1 is a longitudinal sectional viewof a roller skate embodying the features of my invention. Fig. 2 is aview of the under side thereof. Fig. 3 is a section on line 3 3 ofFig. 1. Fig-4 is a rear end view of the skate. Fig. 5 is a section online 5 'of Fio. 1.

In the embodiment selected for illustration, 1 is a foot plate supportedby a frame comprising the brackets 2 connected together by thelongitudinally extending bar 3, which is spaced for the greater part ofits length from the foot plate 1. Each bracket comprises a bearingsocket 4, webs 5, and outstanding flanges 6 which are riveted orotherwise secured to said foot plate. The bracket may be formed of sheetmetal in which event the blank will be bent to form the socket as shownwith the two webs in close proximity and connected by an adjustingdevice, as a bolt 2a whereby the webs may be brought together to take upwear in the socket. The bar 3 may be connected to the respectivebrackets in any well known manner, as by a rivet 3a passed through ears20 formed on the flange 6 and through the bar 3. The brackets supportthe spindle 7 a of the wheel-carrying axles 7. Each axle 7 has fixed toits middle portion a spindle 7 a adapted to lie in the bearing t. Thespindle 7 a is held against withdrawal from said bearing by means of acotter pin 9 extending through said spindle and lying against the upperend of said bearing. An upwardly extending arm 10 is xed to each axle 7by suitable means, such as a plate 11 lying etween the axle 7 and thebearing 4, the spin dle 7 passing through said plate and the latterhaving sleeves 12 thereon which embrace the axle. The axles 7 are heldat right angles to the main frame by means of two leaf springs 13, saidsprings being secured to opposite sides of the bar 3 and between theirrespective ends by means of a bolt 15 and nut 16. The arms 10 attachedto the axles 7 lie between the opposite free ends of said leaf springs.The springs 13 and the bar. 3 are spaced a suitable distance away fromthe foot plate 1, and said foot plate is provided with lugs 17 strucktherefrom, and which bear against the edge of said bar. A yoke 18 andthe bolt 15 extending through said yoke, connect the bar 3 and thesprings 13 to the foot plate. The yoke 18 may be secured to the footplate 1 in any suitable manner, as, for instance, by a rivet 19. Thepivotal movement of the axles 7 is limited by stop pins 21 fixed in theanges 6 in position to be engaged by the springs 13 when the latterareflexed in the rotation of 'said axles in the bearings 4c.

Any suitable means may be provided for securing the skate upon the foot.

It will be seen that a roller skate constructed in accordance with myinvention is very strong and durable; also that the parts are few andsimple, thereby lessening the cost of manufacture.

I do not limit myself to the exact construction herein shown anddescribed, inasmuch as various changes may be made without departingfrom the spirit and scope of the invention.

I claim as my invention:

1. In a roller skate, in combination, a foot plate provided at each endwith a bracket composed of an integral piece of sheet metal bent to forman axle spindle-receiving socket, axles having spindles pivotallysupported in said sockets and having upright arms secured thereto,wheels mounted on said axles, a bar extending between said brackets, andleaf springs secured to opposite sides of said bar and having their endsengaging the upper ends of said arms.

2. In a roller skate, in combination, a foot plate; a bracket secured toeach end of said foot plate, each of said brackets comprising a bearing;means for taking up wear on said bearings; spindles rotatable in saidbearings; axles fixed to said spindles; and wheels on said axles.

3. In a roller skate, in combination, a foot plate, axle-supportingmeans at each end of said foot plate, axles carried thereby, wheels onsaid axles, a spaced barv longitudinally po# sitioned beneath said footplate and carried by the axle-supporting means, and a lug struck fromsaid foot plate and bearing against the spaced edge of said bar.

il. In a roller skate, in combination, a foot plate; brackets secured tosaid foot plate, each of said brackets being formed of an integral pieceof sheet metal bent to form a bearing and a web of double thicknessadjacent said bearing; means for drawing said web together to take upWear on said bearing; and axles supported in said bearings.

5. In a roller skate, in combination, a foot plate; brackets secured vtosaid foot plate, each ol said brackets being formed of an integral pieceof sheet metal bent to form a bearing and a web portion adjacent saidbearing, said bracket-s having outstanding flanges lying against saidfoot plate and downwardly-projecting ears on said lianges; a barconnecting said bracket-s, the ends of said bar being secured betweensaid downwardly projecting ears; and axles mounted in said bearings.

G. ln a roller skate, in combination, a main frame; springs fixed toopposite sides of said frame; spindles rotatably mounted in said frame;axles lixed to said spindles; and arms fixed to said axles, the upperends of said arms lying between and being engaged by said springs, thelower ends of said arms comprising plates lying between said axles andbearings, said spindles passing through said plates, the sides of saidplates being bent around said axles.

7. In a roller skate, in combination, a foot plate; brackets securedthereto; spindles rotatably mounted in said brackets; axles iixed tosaid spindles; arms fixed to said axles; a bar connecting' saidbrackets; springs fixed to opposite sides of said bar and engaging saidarms; and stop pins on said brackets adapted to engage said springsandlimit the rotation of said spindles.

8. A frame for roller skates comprising a foot plate; twoaxle-supporting brackets rigidly secured to said foot plates; a stiftening bar extending from one of said brackets to the other; and spacingmeans between said bar and said foot plate.

9. In a roller skate, in combination, a foot plate;.a bracket rigidlysecured to said foot plate near each end of the latter, each brackethaving an axle soindle receiving socket; axles having spindles pivotallysupported in said sockets and having upright arms secured thereto;wheels mounted on said axles; a bar extending from one of said bracketsto the other and being rigidly secured to said brackets; a bracketsecured to said foot plate centrally of the latter; two springsextending from one of said axle-support-ing brackets to the other, theends of said springs lying at opposite sides of said upright arms, saidsprings and said bar being attached to said central bracket; and spacingmeans between said foot-plate and said bar and springs.
